Unfortunately, Time Machine backs up everything. and I mean everything–like the operating system, the applications, external drives, thumb drives, and more. This can cause backups to be unnecessarily big, and can lead to filling up your backup drive faster than necessary.
One solution to this problem is to exclude things from the backup. I did it like this:

Prevent Spotlight from searching these locationsdialog, click the
+icon and add the backup drive to the list.
